JFK was not the most popular president. He is just the most recognized name because he was killed relatively not long ago in public and had lots of shady characters involved, from the CIA to Carlos Marcella in New Orleans. Remember JFK came into power when there was substantial anti-catholic sentiment in America and up until he was killed he had not had a very successful presidency. Not to mention his family past and current were Drug dealers,bootleggers, and cowards who leave women to drown in cars while they run home to straighten their story. Rip Martha Moxley. Robert Kennedy on the other hand......he had some potential. His biography was far more interesting than Johns.
